LOOM-BEAMl LOCK.

Application filed January 7, 1927.

This invention aims to provide novel means for holding the shaft of a warp beauu in a loom for rotation on the loom frame.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

Vith the ftbOVG and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the let-ails of construction hereinafter described and claimed it being understoml that changes in the precise embodiment of: the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the inven" tion.

In the drawings Figure 1 shows in elevation. a portion of a loom wherein the device forming the sub jcct, matter of this application has been embodied;

Figure 2 is a side elevation; and

Figure 3 is a top plan.

The numeral 1 designates the frame memher of. a loom, provided with an opening 2 defined by edges 3 and 4, located at an angle to each other, there heing a depressed hearing notch 5 in the edge 4. near to the outer edge 6 of the frame member 1. the opening 2 having a reduced extension 7 located at the angle formed by the edges 3 and 4, and there being a projection 8 extended from the edge about parallel to the edge 4-, and located at the upper outer portion of the extension T. Having thus described in considerable detail. the shape of the opening 2 in the edge of the frame member 1. it may be stated that the numeral 9 marks a warp beam having a shaft 10 provided with a reduced end 1 forming a shoulder 12 in the shaft. The shoulder 12 disposed closelv adjacent to the inner surface 14 of the frame member 1, and the reduced end 11 of the shaft 10 is jourualcd for rotation in the hearing notch 5 of the frame member 1].

A keeper 15 is provided. the same including a shank 16 having an elongated slot 17 in which is mounted a clamping and securing device. such as a holt 18 carried lov the frame member 1, the nut 19 on the bolt holding a Washer 20 against the shank 16 of the llcrial No 1.59 668 .lreepcr 1:1. The slot 1i, of eourstn provides for a vertical :wljustulent of the keeper 15. The shard; 16 has a lateral fended llOOlI- shaped arm proviir d with [mending end 5552 the lower or i= er edge of the arm. :21 lacing: couca red as at Shh to cooptn'rte with the bearing notch 51' in holding the reduced end 11 of the shaft 10 for rotation. The upper end of the shank l (1 hcvcled as at and wclendcd laterally, in an o ngosilc dirw-tirm to the arm P21 to form a wing 25 that own-laps the outer surface of the fr a'i'ne menilier 1 at the edge 3. and the shank it; is thickened at its upper end to form a shoulder Qt? to engage the edge 3, the shoulder 26 heing disposed at right angles to the inner surface 27 of the wing .llccausc the slot 17 is providerh the lree 'n r 1:; may he raised and lowered to c. the end of the arm 21 with the redu ad part 11 of the heai'nshnft 1th and then the nut and bolt ill-"-18 may he lllflliltillltlfl no the shoulder 26 en aging the edge 3 of the frame member 1,. at l the wing 25 overlapping the outer surface of the fran'ie member 1. as shown in Figure 3.

The device shown is a solid one-piece lock which fastens on the loom frame with a single holti wear being reduced to a mini: moan and the effective life of the device being lengthened accordingly The device cooperates in an in'iproved war with the let-off gcalx d no to the fact that the gear end of the beam is held perfectlv in n'icsh with the let-off egear vibration heiinr sul'istantia l eliminated. The article is adinstaliilc, so that it will work in a satis'l'ncto, way with either a new henn'i shaft or an old one.

W'hnt is claimed is:

1. In a beam lock for looms. a keeper ineluding a shank provided with an arm and with a wing that projects from the shank in opposite directions. the shank having a shoulder disposed approximotel at right angles to the inner surface of the wing and means for mounting the shank on a loom frame.

In a beam lock for looms a lTPG/DOT' com-- prising a shank having an arm an "l a W ng. the arm and the wine; projecting in opposite di ecti ns. the arm and the Wing l cing spaced apart longitudlnallv of the shank. the shank having a shoulder disposed zip-- Hill proximately at right angles to the inner surface of the Wing and'alined with the wing, transversely of the shank, and means for connecting the shank with the frame memher of a 100m.

3. In a beam lock for looms, a keeper comprising a shank having an elongated slot, the shank being provided with an arm and a Wing, projecting in opposite dirvrtiona. and the shank having a shoulder disposed an proximately at right angles to the inner snrfaoe of the Wing.

In testimony that I ciailn the imag ning as my own, I have hereto affixed my signature.
